My 3 x gt grandfather ROGER PRICE was a shoemaker. I first found this out from his son's marriage cert (1862). I have found a possible entry in the 1881 census - boarder age 76, shoemaker, born Llangefni. there is an equivalent entry in 1871 - listed as Robert Price, shoemaker, Llangefni, Lodger, age 67 born LLanddyfnan. I haven't had any success prior to 1871. This will prompt me to look again!
